Question: What is the fourth dimension?
Asked by c6h12o6 to Evan on 24 Jun 2011.
answered on 24 Jun 2011:
The first three dimensions are: up-down, forward-backward and left-right. The fourth dimension is time (past-future). Good question!

How long is a cosmological decade?
How do you think the universe started?
